I have lavender, Thyme and a couple of other plants in my garden which are nice smelling ones. Last year I had Jasmine which smelt nice sometimes (usually when it was watered I think) but my problem is that unless I go and rub them I just can't smell them, even when I do that it lasts 2 minutes or so then nothing. So why is it that when I walk past certain gardens I can smell them and they're lovely? There are 2 front gardens I regularly walk past, one smells of Lavender from about 3 doors down each way and one smells like Jasmine I think. I've looked in the Lavender garden and it looks like standard English Lavender which I have (also the purple flowery ones which I think are French Lavender). I can smell Thyme on a warm day outside a house we pass also so any ideas why mine doesn't smell at all?
